COVERING: SAFETY PRECAUTIONS & PLACING INTO SERVICE
AIR OPERATED ORBITAL SANDERS
It is the responsibility of the employer to place this information into the hands of the operator.
AIR SUPPLY REQUIREMENTS
For maximum operating efficiency, the following air supply specifi-
cations should be maintained to this air tool:
•
MAXIMUM AIR PRESSURE -- 90 p.s.i.g. (6.2 bar)
•
AIR FILTRATION -- 50 micron
•
LUBRICATED AIR SUPPLY
•
HOSE SIZE -- 5/16" (8 mm) I.D.
An AROR model C28231--810 air line FILTER/REGULATOR/
LUBRICATOR (F.R.L.) is recommended to maintain the above
air supply specifications.
An AROR model P29231--110 air line FILTER/REGULATOR plus
100067 gauge is recommended to maintain the above air supply
specifications.
Always use clean, dry air. Dust, corrosive fumes and/or excessive
moisture can damage the motor of an air tool. An air line filter can
greatly increase the life of an air tool. The filter removes rust,
scale, moisture and other debris from the air lines. Low air pres-
sure (less than 90 p.s.i.g., 6.2 bar) reduces the speed of the air
tool. High air pressure (more than 90 p.s.i.g., 6.2 bar) raises per-
formance beyond the rated capacity of the tool and could cause
injury. Shown below is a typical piping arrangement.

WARNING
Lack of or an excessive amount of lubrication will affect the per-
formance and life of this tool. Use only recommended lubricants
at below time intervals:
EVERY 8 HOURS OF TOOL OPERATION - - Fill lubricator res-
ervoir of recommended F.R.L. with spindle oil (29665). If an in
line or air line lubricator is not used, apply several drops of
spindle oil (29665) in air inlet.
MODELS 8444- -( ) - - EVERY 40 HOURS OF TOOL OPERA-
TION - - Flush tool with a solution of three (3) parts cleaning sol-
vent to one (1) part spindle oil. After flushing, apply a small
amount of spindle oil in air inlet and run free for one minute to
insure proper lubrication.
MODELS 8448- -A( ) - - EVERY 160 HOURS OF TOOL OPERA-
TION - - Flush tool with a solution of three (3) parts cleaning sol-
vent to one (1) part spindle oil.
Air line debris, moisture and carry--over oil from the compressor
can restrict the muffler and leave contaminants in the motor. Every
160 hours of tool operation, or sooner if motor speeds drop below
accepted speed, flush the tool with a solution of equal parts of
cleaning solvent and spindle oil.
EVERY 160 HOURS OF TOOL OPERATION - - Inject grease
(33153), one or two strokes, thru threaded end of spindle for lu-
brication of needle bearing contained in counterbalance. Sanding
pad must be removed from spindle to allow injection of grease.
INSPECTION AND MAINTENANCE
It is important that the tools be serviced and inspected at regular
intervals for maintaining safe, trouble--free operation of the tool.
Be sure the tool is receiving adequate lubrication, as failure to
lubricate can create hazardous operating conditions resulting
from excessive wear.
Be sure that the air supply lines and connectors are of proper size
to provide a sufficient quantity of air to the tool.
Tool maintenance and repair shall be performed by authorized,
trained, competent personnel. Tools, hose and fittings shall be re-
placed if unsuitable for safe operation and responsibility should
be assigned to be sure that all tools requiring guards or other safe-
ty devices are so equipped. Critical rating markings on the tool
shall be kept in legible condition. Maintenance and repair records
should be maintained on all tools. Frequency of repair and the na-
ture of the repairs can reveal unsafe application. Scheduled main-
tenance by competent authorized personnel should detect any
mistreatment or abuse of the tool and worn parts. Corrective ac-
tion should be taken before returning the tool for use.
